Question
A uniform, 0.0300 kg rod of length 0.400 m rotates
in a horizontal plane about a fixed axis through its
center and perpendicular to the rod. Two small
rings, each with mass 0.0150 kg, are mounted so
that they can slide without friction along the rod.
They are initially held by catches at positions
0.0500 m on each side of the center of the rod,
and the system is rotating at 48.0 rev/min. With
no other changes in the system, the catches are
released, and the rings slide outward along the rod
and fly off at the ends.
